of any diameter to bottles, jars or other eontainer and it is my objecttoproduce a machine in which the pressure, while sufficient toaccomplish the not rise high enough to break the result, will container,which can be adjusted to cap containers of different heights, whichwillcompensate for countered variations of the containers enincommercial operation an which will cap a container although the same mayhave been positioned 'on the table in such manner as to lnltiallyreceive pressure on but a portion of the cap. In the drawing Fig. 1 is amy machine; Fig. 2

front view of a side view thereof and Fig. 3 a sectional view of thefeed table on the line 3'3 of Fig. 1.

. The machine, comprises supporting a table frame 2 which may be raisedor lowered by loosening the bolt 3 and turning the screw feed 4:. Thisadjustment is used principally to aline the table .with the fillingmachine.

This table frame carries a plurality (5f rollers 5 and drums 6" 6 ateither end thereof, the upper surfaces of the drums and rollers all ning.

belt 7 passes over the rollers and drums, a tensioning' device 8 beingprovided to keep it taut.

Located over the table and on themain frame is a pressure applying headblock 9 vertically adjustable by a This block carries a pair and 12,each of which has a gear 14) secured thereto of gears feed screw 10. ofcrank disks 11 13 (and and also carries a train 15'which transmit motionfrom one crank disk to the other.

Suspended from disks are a pair of the pins on the crank links 16 and 17whose lower ends are rigidly secured to a plate 18.

A presser plate 19 the plate 18 by pairs of cured to the plate the plate18 with spring between the plates.

is yieldingly secured to studs 20 and 21, se- 19 and passing through s22, 23 interposed ThlS permits the plate 19 to yield upwardly withrespect to the plate'18.

To revolve the crank disks 11 and 12 a main drive shaft 24 is journalledonthe mawith a'bevel gear 26 which is journalled on the frame. A splined shaft 27 passes through the gear 26 and is free to slide thereinbut revolves passing through a therewith, the lower end bearing 28 onthe bee u to machines for apd or lowered without a "main frame'lcontainers pass under the sealing block '9 and carries abevel gear 29which disk 12. a

As the shaft 24 is revolved it will revolve the shaft 27 and revolve thecrank disks with their gear train transmitting the motion from one diskto the other.-

shaft 27 permits the head block tobe raised transmission of power.

To drive the feed table belt a gear 3l,secured to the gear 26 mesheswith a gear32 also joilrnalled on the main frame. A splined shaft 33passes slidably through the gear 32 and has its lower end in a bearing34 on the table frame 2. A gear 35 on the shaft'33 meshes with a gear 36on the drum 6. As

the shaft 33 is revolved the drum 6 will drive the belt 7 and cause itto travel under the presser head and over the supporting rollers 5. y

The speeds of the shafts 27 and 33 are so calculated that when the plate19 is in its lowest position and in contact with a cap on a container itwill be travelling laterally at the same speed as the belt 7.

The operation of the machine is as follows :-The table is set level withthe filling machine to receive the filled containers. The sealinghead isadjusted up or down so that the plate 19 will exert a driving, sealingpressure on the caps, which are loosely laid on the containers, as thecapped containers pass under the head. As the loosely capped head whichis moving up and down'and laterally: due to the crank motion, the plate19 forces the closures tightly onto the containers. The

the plate 19 to yield under'pressure and prevent breakage of thecontainers. They also act as compensator-s for containers of slightlyvarying heights.

"If a container is placed on the belt at such time as the plate '19 willnot press on the entire surface of the closure the next stroke of thesealing head will engage the entire closuie because the plate 19 is ofsufficient length, and the speedof the belt is such that .each closuremust receive a full area pressure stroke before it has travelled fromone side of themachine to the other. I claim 2- 1'. A machine foraflixing closures to cond tainers comprising a frame, a pair of drums,

The slidingsplined connection between the gear 26 and interfering withthe said belt, a pair of crank diskson said head,

' -crank pins thereon, links suspended from Said pins, a presser platerigidly secured to the lower ends of said links, me ns for moving saidpresser head vertically, a drive shaft journalled on said frame, a gearjournalled on said frame, a shaft passing through said gear andsplined'thereto, a gear on the lower end of the shaft engaging the drumgear, means for driving said jofirnalled frame gear from the drive shaftand for rotating the crank disks in synchronism with the splined shaftwhereby the belt and presser plate will travel laterally at the samespeed when the plate is" in contact with a closure.

2. A machineffor afiixing closures to containers comprising a frame, adrive shaft and a gear thereon on said frame; gears journelled to saidframe one of which engages the drive shaft gear, a head block mounted onsaid frame, a pair of crank disks on said block, a gear on one of saiddisks, means for transmitting motion from one disk to the other, a shaftsplined to the journalled gear engaging the shaft gear, agear on thelower end of said shaft engaging the disk gear,

the lower end of the second shaft engaging the drum gear whereby thebelt and presser plate are synchronously driven so that their lateraltravel is the same while the presser plate is in contact with a closure.

In testimony whereof I have affixed my signature.
